Food: Greek, Thai, Japanese, Middle Eastern, Mexican (basically everything)
If these date ideas (and order) doesn't terrify you:
1) Building elaborate Lego castles while sipping on Pinot Noir.
2) Going to the Natural History Museum to discuss/debate the personalities of each and every dinosaur.
3) I haven't planned the third date yet but am very open to suggestion (and very willing to come up with more creative ideas).
